Hydroxylbastnäsite is a rare cerium carbonate hydroxide mineral. It typically forms in small, prismatic or tabular crystals with a pale to brownish color and a subtle vitreous to resinous luster. The mineral often occurs in cavities within peralkaline rocks or hydrothermal veins, where Ce-rich fluids crystallize under low to moderate temperatures. Crystals can be fragile, and habit may include elongated prisms or rhombohedral forms, sometimes displaying a gentle internal sheen when clean.

About Hydroxylbastnäsite
Specimens are chiefly associated with classic bastnäsite-bearing districts and sites that have yielded cerium-rich carbonates, where hydrothermal processes concentrate rare earth elements. While not abundant, hydroxylbastnäsite is valued for its rarity within the cerium family and for the visual appeal of its modestly colored, well-formed crystals. Collectors prize specimens that display good crystal form, clean faces, and minimal association with other more common minerals, as these pieces emphasize the mineral’s delicate character and distinctive chemistry.
